Descend into Seattle’s original street level beneath Pioneer Square for a one-hour guided walk through brick passageways, rebuilt streets, and the layers of the city’s past. Learn why Seattle raised its streets after the Great Fire and how those underground corridors survived into the present.
More ways to explore the area's outdoor wonders
You step off the sidewalk and descend dim wooden stairs into a world that once sat at street level—brick corridors, narrow passageways, and the faint echo of late 19th-century footsteps. Light pools from grate-covered openings; the air is cooler and smells faintly of old timber and stone. Guides move with practiced ease, pointing out patched brickwork where the city literally built a new street above the old one after the Great Seattle Fire of 1889.
